The time required to recharge a battery depends upon:

Charging time hinges on how much energy the battery still needs and how fast energy can be delivered. The energy needed is set by the battery’s current state of charge and its rated capacity—the total energy the battery can store. If the battery is deeply discharged, more energy is required, so charging takes longer; a larger capacity battery stores more energy, extending the time to refill. The charger's amperage output determines how quickly energy is delivered, so a higher current can shorten recharge time within the battery’s acceptance and thermal limits. Temperature can affect charging efficiency, but it doesn’t change the fundamental relationship as much as the charger’s current, the state of charge, and the battery’s capacity. The vehicle size or battery color do not determine recharge time.
